Addendum I
Additional Instructions for
Eagle Cuda 240i S/GPS
Your sonar/GPS unit, the Cuda 240i, functions exactly like the Cuda
240 described in the manual provided (part 988-0152-012). In addition,
the Cuda 240i contains a communications port for NMEA 0183 output.
The instructions for connecting data cables and setting up the
communications port appear in this addendum.
NMEA 0183 Data Cable Connections
NMEA is a standard communications format for marine electronic
equipment.

A few other radio brands (and other electronic devices) that meet the NMEA 0183 standard won't need these adapters and you will have to remove the resistor and diode to make those work. This is Wiring Diagram B, which is described on page 4. Consult your other device's owner’s manual, then read through all of the following instructions before you begin. Use the installation diagram most suited to your brand of radio or other device. If your device manual indicates an RS-232 connection (i.e., a c

Twist the exposed wires together as shown in the following figures. If you're using a Uniden or similar radio, connect the radio's NMEA Wire to the Cuda 240i data cable's yellow wire, and the radio's Ground/Shield wire to the Cuda 240i data cable's black shield wire. If you're using another radio brand or NMEA device, see Wiring Diagram B instructions at the end of page 3.

After taping the wire ends individually, wrap the entire connection with electrical tape as shown. This will help protect from moisture and prevent the wires from breaking contact. Wiring Diagram "B" If your VHF radio or other device requires true RS-232, you will need to remove the diode and resistor built into the end of the Cuda 240i data cable. You will notice near the end of the cable a segment protected with black heat-shrink. To connect the Cuda 240i to a true RS-232 radio, first remove t

After you've removed the adapter segment, use wire pliers to expose the ends of the five remaining wires in the cable. Cut off the black, blue and white wires, then seal their ends with electrical tape. Black Cut black, blue Blue and white. White Yellow (transmit) Bare wire (shield) After removing the adapter segment, prepare to connect by removing and taping off unneeded wires. Strip the end of the yellow wire. Strip about 1/4-inch (6.35 mm) of insulation from the yellow wire, then follow th
